To all whnnt it 727/011] concern: 1

Be it known that I, Louis SCIILESINGER, a citizen of the United States, and a resident of l the city and county of Milwaukee, State of i \Visconsin, have invented certain new and E useful improvements in Spacin Mechanism for 'lype\'\"riting Machines, of which the l'ollowing is a full, clear, and exact description.

In typowriting machines, whether of the style in which the. paper carriage or support is nmvahlrwith respect to the printing nuzchanism, or that style in which the sheet or book to be written upon is held upon a stationary support over which the printing mechanism is caused to move, it is desirable to provide means whereby the movable part or member may be arrested at any one of a number of fields" or groups of letter-spaces along its line of travel, as distinguished from mechanism adapted to merely effect the arrest of the movable part or member at any one of a plurality of points arranged at letterspace distances apart as in ordinary tabulating machines.

The primary object of this invention is to provide improved mechanism (independent of tabulator devices, which may or may not be used in conjunction therewith), whereby per support or movable part at any one of a number of column fields located along the path of travel of the paper support or movable part, and the invention consists in the features of improvement hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of this specification.

Figure l is a view in side elevation of a typewriting machine embodying the invention, the left-hand side of the main frame of the machine being broken away. Fig. 2 is a view in horizontal section on line 22 of Fig. 1. Fig. 3 is a view of the machine in rear elevation, parts being broken away and parts being shown in vertical section. Fig. 4 is a view 'iii vertical cross-section (from front to rearl through the rear portion of the mechanism, the view being taken on line ;4 of Fig. 3. Fig. 5 is a detail front view, 1. e.,-lool ing toward the rear) of the do carrier at the back of the machine, certain o the adjacent parts being shown in vertical section and other. parts being shown in elevation. Fig. 6 is a lan view of the rear portion of the machine. l ig. 7 is a detail inverted plan view of the Fig. 8 is a detail view in stop-carrying bar.

Fig. 10 is a lan view of the rear portion of the top of t 10 main frame and of cer-, tain parts carried thereby, the carriage mechanism being omitted and the pawl carrier and certain adjacent parts being-shown in horizontal section. Fig. 11 is a view in vertical cross-section (-i. e., from front to rear) throu h the rear portion of the machine, this view being taken on line 1111 of Fig. 3. Fig. 12 is a view in vertical cross-section (i. e.,

' from front to rear) through the rear ortion of the-machine, parts being omitted, certain arts being shown in elevation and the tabuator mechanism being shown in position.

In the accompanying drawings the invention is shown as applied to the well-known Remington No. 6 typewriter, although it will be understood that with more or less modification it may be used in connection with various other styles of typewriting machines. I wish it distinctly understood, therefore, that while I have illustrated in the accom anyi-ng drawings and shall now describe w at I regard as the preferred embodiment of the invention, extensive modifications may be made by the skilled mechanic without de parture from the scope of the invention, and eatures of the invention may be employed without its adoption as an entirety.

A designates the frame of 8. Remington typewriter, upon the top-plate of whichis mounted the usual paper-carriage B that is provided with the platen C Whereon is supported the paper to be printed. The papercarriage B is shown as provided at its rear with the usual pivoted rack bar D, the downwardly-facing teeth of which are in normal engagement ,with the teeth of the escapement pinion I). This pinion D is mounted in the ordinary mhnner upon the inner end of a shaft d at'the back of the top-plate of the machine, the rear end of the shaft carrying the usual escapement ratchet wheel cl, with the teeth of which engage the escapement awls or dogs d and d that are vibrated by a ever d, as will readily be understood by those familiar with this style of machine. The rack bar D is ivotallysupported in; the usual manner set at it may be disengaged from the teeth of the pinion-D. As SllQWI'l the rear part of the carriage B is provided with bearing rolls b that travel upon the back rail (2 which extends from side to side of the machine across its top, and thesebearing rolls 1) are j ournaled in the back art o'f the frame of the carriage B. From t is carriage B projects rearwardly an arm B that en gages a rail b extending across the top-plate of the main frame at the rear of the carriage and beneath this rail'is mounted the usual bar 5 whereby the margin-stops will be carried. The mechanism thus far described is that found in the familiar No. 6 typewriter and without more precise description its construction and operation will be readily understoodby those familiar with this class of machine.

To the back of thepaper-carriage B is connected a frame E (see Figs. 1 and 6), the inner depending arms e of which are bolted to the rear of the paper-carriage as at e. As shown, 7 the frame E is formed with rearwardly-extending arms 6 that serve to carry a stop-bar F. The stop-bar F is preferably adjustably attached to the frame E and for this n ose the arms e -of theframe are preferab y 'ormcd with slots a throu gh which pass the screws e that enter threaded holes in the ends of the bar F. The stop-bar F is preferably formed upon its front and rear edges with notches located at letter-space distance apart, these notches being adapted to receive the bifurcated portions of the col- V umn field-stops G and to receive also the bifurcated portions of-the denominational stops H, if these latter stops be used. The purpose of adjustably supporting the stopbar F is to enable its-notches to be caused to register accurately with the letter-spahe scale of the machine and it will be readily a correspondingly dove-tailed locking plate F. One end of this locking plate F is provided with a pin or offset that is engaged by the notched end of a lever F that is pivoted as-atj" within a slot formed in the end of the stop-bar F. The locking plate F'is formed upon one side with notches and ribs corresponding with the notches and ribs of the stop-bar F -and adapted to aline there with when the column-field stops and the denominational stops are to be placed inosition; but by shifting the lever F the loc 'i'ng plate F may be moved slightly lengthwise so as to cause the ribs of this locking plate to come opposite the notches of the stop-bar F. Bv reference to Fig. 4 of the drawings it I will be seen that the column-field stops G (and the same is true also of the denominational stops H.) are formed with notches g and when the locking plate is shifted as last described, the ribs or projections of this locking plate will enter the notches g of the stops G (and as well also the notches of the denominational stops H) and will thus prevent the movement of the stops from the position in which they have been set. When, however, it is desired to remove the stops, the lever F will be shifted so as to bring the ribs or projections of the locking plate F in vertical line with the ribs of the stop-bar I", thereby permitting the column-field stops or the denmninational stops to be withdrawn. The denominational stops ll are designed to co-operate with the tabulating mechanism to he hereinafter briefly described, and the column-field stops are designed to co-operate with the mechanism to be next described, whereby the arrest of the paper-carriage may be effected at any one of several predetermined points along the line of print.

By reference more particularly to'Figs. 1, 2 and3of the drawings it will be seen that adjacent one side of the main frame of the machine extend two key-levers J and K. As shown, the key-lever J is journaled in the usual manner upon a depending rib j at the back of the machine, and the key-lever K is ivoted as at k to the rear end of the lever J, oth of these levers J and K being forced normally upward by the usual platespring 4 that is mounted upon a bar 5 extending transversely of the machine near its back.

A series of field-stop finger-keys M, M, M M, M mounted one above the other at one side and transverselyof the keyboard,

with their 11 right stems m extending through fixed s eeves m and resting upon the forward end of lever K to be normally up held thereby. Keys M, M, M M, M are arrested, when pressed down, by the upper ends of sleeves m, which thus act as stops and which are so graded that the several keys will have substantially a uniform throw. If any key is depressed a uniform throw is imparted to lever K, which operates the release and may be termed the release lever. The adjacentlever J ,has at its forward end a series of graded steps j with which engage collars m adjustably threaded on stems m of keys M, M, etc. Collars m are arranged .at varying-distances above the respective steps j so that-a variable throw will be imparted bythe several keys to lever J, which controls the stop dog and may be termed the dogoperating lever. In other words, the several keys actuate dog-operating lever J with varying degrees of lost motion to impart there to different extents of depression, whereby the stop-dog may be variably shifted, as will presently appear.

35 screw 25 beingadapted tocontact with the (see Figs. 1 and 2) is fastened aframe or plate 7 6 having at its ends upwardl extending 's 7 in which is journaled 'a s aft 8. On '.th1s shaft is loosely mounted av sleeve 9 having fixedthereto a rearwardly projectin arm 10. To the shaft S isfiired alever 12 t sinner end of which is formed" with a slot 13 (shown by dotted lines in Fig. 1) and has pivotally connected thereto the upper end of a 1 link 14.; The lower portion of the link 14.' (see Fig. '3) is formed with a slot 15 through' which passes a headed pin 16 .that connects 'the'link to the lever J. The lower end ofthe link 14" is turnedinwardly as at 17 and formed with a threaded'ihole" through which passes an adjusting screw 18 and preferably a threaded jam-nut 19 holds the screw 18in P ace when it hasbeen adjusted, the screw 1'8 being arranged to contact with the lower edge of the lever J. Thepurpose of the screw 18 is to accurately determine the movement imparted. by the lever J to the .parts controlled thereby. From the outer face of the 1 lever K projects a pin 20 adapted to enter a slot 21"that is formed in-the lower portion of a link 22, the upper .portion of which-link is bentrearwardly and is pivotally connected as at 23 to the rear end of a rock-arm 24 that I 39 is fixedto the sleeve 9 revolub'l'y'mounted on the shaft; 8. 1 The lower end of the .link 22 is bent inwardly beneath the lever- K, as shown 7 in Fig. 3, and is formed witha threaded hole to'receive a set-screw 25 that is fiirnished with a jam-nut 26; the upper end of the set-- lower edge of thelever To one side of the lever K is attached a plate-spring 27, the free end of which enters 'a notch .in the edge of the '40 link 22 '(see Fi 1),"the spring 27 thus serving 1 tohold the ll 22' in its uppermost position. By adjustingscrews 18 and 25, which engagerespectively with levers K and J, the extent of movement of'the parts controlled by the levers, may be acc'uratelydetermined.

From the foregoing description it will be seen that when any one of the finger-keys M, M, etc., is depressed, it will force down both, the operating lever J and the releasing lever 5 o a K and the operating lever will carry downward the link 14 and b ymeans of the rock-arm 1 2,-

s will cause'th e shaft 8 to rock, whi1e at the ings, it wi I ,.same time the downward movement of the leverK will force downward the link 22,

l 5 5 which, being connee ted'by the arm 24 with I the sleeve 9, will cause .the sleeve'tol turn about the shaft 8 and will cause the rock-arm 10 to' move downward. By reference more particular? to'Figs. 2, 3 and elof the draw-J be seen that the shaft 8 has connected thereto a rock-arm '30, to the free end of which is pivotally connected as at315'the lower end 0 a rod32, p 1 v The rod 32 extends upward'Jthrough a bracket 33 that rises from the plate or frame,

To theba'ck'portion a of the main frame 6 and the upper end of the rod has fixed thereto a plate 0 having ratchet teeth 0,on one of its edges. As shown, the plate 0 is movable longitudinally between. a plate 0 and a plate 0 the plate 0 having correspond-' 7 0 ing ratchet teeth on one edge. The plates 0 and O 'are connected together and constitute a carrier for the dog P that is preferably formed separate from the plates and is ad- I justably connected thereto by a set-screw p 7 5 that'passesthrough a slot 1) of the dog P and enters' a threaded hole in the upper end of the plate 0 i To more securely hold the dog P position, it preferablyforined with teeth adapted to engage similar teeth 0 formed on carriage can be determined, it being-under stood that the dog P is adapted to contact with the depending lower ends of the columnfield stops G'above it,;as willpresently more fully appear.- The plates 0 and. O are. mounted to slide within 'a frame R (see Figs. 9o

3 and 4) the back of this frame being formed witha slot 1" through which'passes a screw 35 that enters the plate 0. The frame "R has a ho'rizontally-projectin portion r that rests upon and is bolted to t e rearofthe top-plate 9 5 i of the'main-frameA (see Fig.4), and the upper partof the frame R is formed-with a re'ar- Q wardly-projecting portion r that rests upon and is'bolted' to a brackets (see Figs. 4 and 6) that is fastened to a back rod b extending Leo; across thetop of the mainframe ofthema-f;

chine at its rear. The downward movement of the dog P. and dog holder 0 O is limited bythe engagement of-the screw or stud 35 with the lower end of the slot 1". The plate 0' -1 e5. is provided at its lower end with a shoulder O that' is arranged to engage the lower edge of the plate 0 when the rod 32 is shifted vertically. Normally this shoulder is spaced] as "shown in Fig. 4, slightly apart fromthe 1 ref lower edge of the plate 0 To the upper part of the rod 32 is fixed a collar 36to which is attached the upper .end of a, coil-spring 37, the lower end of this spring being attached as at 38 tothe bracket 33 (see Fig. 3), and

this spring 37 serves' 'to draw downward the a plate 0 to normal position. If found necessary a second spring may be attached to the dog carrier 0 O to hold it in lowermostposition.

.By reference to Fig.- 3 of the drawings, it no will be seen that the column-field stops 5Q haveftheir. lower ends depending to different distancesfro'i'n the bottom of thestop-barFt and the stops willbe arrangedprogressively, the longest sto G being nearest the right-l e 5 hand end of t e paper-carriage while-the shortest stop, is nearest the left-hand end of the ,aper -carria e. Now by reference more part cularly to s. 1-'-5 of the drawings, it

wilibe seen that i. one-of the fingetrlgeyaltt :30

for example, be depressed, it will force downwardthe dog-operating lever J'and lever K. The operatinglever J will rock thewshaft 8 and will causethe rod 32 to lift the plate vertically. When the lost motion between the shoulder O at the base of the, plate 0,

- and the lower edge of the plate (v)? is taken,

the dog-carrier is lifterhthus raising the dog P, and inasmuch as collar m. of the Iingenkey M is normally in contact with'the dog-open atin leverll, it will impart 'a long n'ioveinent to t e dog-operating lever and will consequentlylift the dog-carrier and dog .P to their highest point where the dog willbe in positionto engage the shortest of the columnfield stops G on the stop-bar F. On the other hand, if'one of the other finger-keys,

M for example, be depressed, it will impart a much shorter vertical movement to the dog-carrier and dog P, both because of the greater distance of the key M from the fulerum of the do -operating lever J, and also because of the oeationof the collar on that contacts with the lever J at a distance from the edge of the lever J. In other words, the varying degrees of 1nst-1notion between the finger-keys and the dog-operating lever insure different extents. of movement to the dog-carrier and dogP and hence cause the dog to be lifted the different distances necessary to enable it to properly engage the different column-fieldj stops G upon the stopbarF. In this way the operator, by depress ing any one of theifinger-key's M, M, etc,

can cause the paper-carriage to be arrested. 7 at any predetermlned point of its travel.

' In order to retain the dog P in raised position after it has been lifted by the depression of any one of the finger-keys M, M, etc., and

thus avoid thenecessity of the operator hold 1 ing his finger upont he depressed key, I provide a check pawl 40 that is pivotally mounted as at 41 upon. the frame R,'a coil-spring 42 serving to normally force the upper end of the pawl etO'into engagement wit the teeth 0 of the dog-carrieri Hence it will be seen that a hen the dog-carrier and'dog P are lifted in manner before described, the pawl 40 will engage the teeth 0 and will temporarily hold the dog-earrier and the dog actu ating member in raised position after the release of the'finger-key whereby the lifting of the dog hasbeen effected.

\ In order to effect the free run of the carriage from right to left after the dog P has thus been lifted to position to engage one or anotherof the columnfield stops G, I prefer to employ the mechanism next to be described. x K

To the rock arm 10 that pro ects rearwardly'rrorn the sleeve 9 (see Figs. 1,2 and Bl/is pivotally connected as at 45 the lower endof arod 46 that is preferablyprovided with a turn-buekle,47 for adjustment, and

the up er. end of the rod 46 is flattened and formed with a slot 48 through whlch passes spring t.

be readily controlled. that when one of the finger-keys M, M, etc., has been depressed, thereby ressing down' ward the forward end of the evers'J and K and raising the dog-carrier and dog P in a headed pin 49 that projects from the tail of a release pawl 50. LrThe pawl 50 is pivoted as at 51 upon an. arm r5 depending from. the

frame it and the-upper end of the pawl-50 formed with a shoulder 52 adapted to engage the rearend of a release lever T'whereby the carriage rack-D (see Figs. 6 and 10) will be lifted from engagement with the escapement pinion D. The release leverTis 1votally n1 ounted upon-a rod t in abracket t at rises from the plate 7' of the frame R (see Figs.

4 and 10), and the inner end of the release lever T is forced normally downward by a The inner end'of the release lever T carries a release plate 6 that extends beneath the carriage rack bar D, so that when the inner end of the release lever T is raised by the depression of its outer end, it will throw the carriage rack D from engagement with the escapement pmlon D and thus permit the carriage to run free from right. to

left until the dog P that has been raised by the depression of one of the finger-keys M, M, etc., contacts with its corresponding columnfield stop G. To the rearend of the release lever .T is connected the upper end of a coilsp-rin'g 55; the lower end of which spring is attached to a rod 56 (see Figs. 1, 3 and 11),

vthelower end of this rod 56 being attached to an offset arm 57 that projects laterally from the lower end of the rod 46. Prefer ably,

thevupper end. of the coil-spring 55 is con' nected to therear end of the release lever T (see Fig. 11) by means of a U-shaped plate manner her einbefore described, the rockarm 10 will be turned downward by the link 22 rocking the sleeve 9. movement of the rock-arm 10 will cause the rod 56 to place the spring 55 under tension,. thereby exertlng a pull upon the rear end of the release lever T; In'asmuchhowever, as the check .awl 50is atsuch time in engagement with t e rear end'of the release lever T, the tension placed upon the spring55 does not move the release lever T until the rock- ,arm 10 has-so far moved downward with the link or rod 46 as to cause the upper end of this rod, to-engagje with the pinor screw 49 and thus swing the check awl 50 about its pivot point 51 until the s oulder 52 of the ICC By means of this This downward pawl is disengaged from the rear'endof the I release lever T, In other Words, the slot 48 in the upper eiid'ofth rod 46 allows a lostmotion of the pawl-releasing mechanism, 1 0

while the s ring 55 is being'placed under tensionin rea iness to shiftthe release lever T. This release of the check pawl 50 (determined accurately by adjusting turn-buokle47) will -F; and-when the dog v and the shoulder 52 ofthe check pawl withdrawn from beneath the rear end of the occur at the time that the dog-carrier and dog Preach the-limit of their upward movement, when the dog P will be in 1position to engage its correspondin stop of t e stop-bar has been thus raised carriage may run free from ri ht to leftuntil has been effected.

its movement is checked by t e engagement of one or another of the column-field with the raised dog P." By this arrangement, the escapement release-occursat the end of the downward movement of lever K and rod 46 and this movement, as stated, is

uniform if every key is depressed, so that the release is invariably actuated at the end of the down stroke of anykey, at which point the dog has been shifted to the" required height for arresting the carriage at the desired field. In other words, in spite of the variable shift imparted tolever J and dog P by keys M, M, etc, a uniform shift is ed to lever K, so that the release is invariably operated, but not until the; end of such uniform throw and'not until-:dog P has been A premature raised to the desired height. release of the escapement-i's thus prevented and carriage B is invariably arrested at that stop corresponding to the key depressed.

The check pawl 50 isnormally forced tol ward the position to engage the rear end of, the release lever T by a spring 58, one end of which is connectedto'the plate 1' (see Fig.

, 3), While the opposite end of this spring bears on the .tail of the pawl 50. As soon as therelease lever T has thus been drawn down to disengage the rack-bar of the paper-carriage from the escapement pinion, a pin depending from a lever 61. (see Figs. 8 and 6) will swing above the rear end of the release lever T- and hold-the lever in the depressed. position notwithstanding the operator may have .liftedhis finger frorn the finger-keys M, M, etc., whereby the operation of the parts As shown, the lever 61 is pivoted upon a stud 62 that risesfrom the plate 7 of the frame R and this lever 61 is provided with an arm 63 that extends rearwardly to a position in front ofan arm'64- (see Figs. 10 and 12) that extends upward from the rocking arm (3 whereby the escape-' .rnentpa'wls or dogs are carried; A spring 65 tends to normally turn the lever 61 so as to cause the pin 60 to swing over the rear end of the release lever T.

Assuming the dog-carrier and the dog to stops impart- .capement ratchet wheel d have been raised by one ofthe keys Mi,-

etc'., as above, described, it will be seen "that a letter we numeral, such depression of the j finger-key will cause the escapement mechanism of the machine to be actuated in the usual manner and at thefsame time will cause the arm 64 (see Figs. 'IO 'and l2) toswing-for- ,ward' and thus turn 'the lever 61 until the pin 60 passes from the rear end of the releasing lever T. This swingingmovement of the le; ver 61 will cause its armthat carries the .pin

60 (see Fig 5) to contact with the lower end of the pawl 40, thereby swingin this pawl about its pivot point 41 and re easing the pawl from engagement with the teeth 0 ofthe dog-carrier. When the pawl 40 is thus disengaged fromthe dog-carrier the spring 37 (see Fig. 3) will retract? the dog-actuating means and permit the dog-carrier and dog to return tomorinal position andwill allow the paper-carriage to be advanced from rightto left as the usual keys of the machine are operated to print their characters. I

By reference more particularly to Figs. 4, 5 and 10.of the drawings it will be seenthat the inner face of the dog-carrier (i; e., ill re plate 1 O) is formed with'a cam-shape recess 0? into which normally projects the free end of an arm 70 that is pivotally mounted upon a stud 71-that rises from the. platej'r of the frame R, the free-end of the arm 70 adapted to cooperate with the-lower edge of the slot 0 'A s ring 72 serves'to force the arm 70 normal y; toward the dog-carrier.

Upon the arm 70 is .fixeda detent arm or pawl 75 of spring-metal that is adapted to be shifted. laterally by the-arm 70 over and into engagement with the .teeth of the escapement ratchet-wheel d inorder toficheck'any;

overthrow movement of the ratchet wheel after the release lever T has disengaged the rack-bar D from the 'escapement pinion D on the inner end of shaft d in manner before described. In the normal position of the dog-carrier, the free end of the arm 70 is within the notch 0 but when the dog-carrier is lifted, its end is struck by theinclined face- 0 ofthe" noteh and the arm 70 is swung for-'- ward ly,

thereby' causing the detent 75 to.

swing over. and into engagement with the teeth of the ratchet escapement wheeld on the outer end of shaft (1. As soon however, as .the dog-carrier is released'and caused to descend, the spring 7 2 will'reversely shift the l arm 70 and detent 75, so as to cause the detent to ;pass from engagement with. the estoo rapid movement of the carriage but when In order to-preventthe too rapid movement of the paper-carriage from right to left when the dog-carrier and dog P have been ,lifted as before described, I prefer to em loy the brake mechanism next to be descri ed, reference being had more particularly to Figs. 3 and 4 of the "drawings. Within brackets that rise from the transverse bar 0. at the back of the machine, is pivotally supported a brake-lever W, the upper arm of which extends beneath the horizontal plate of the frame E and carries a friction roll w adapted to bear against the under side of such'plate. The lower arm of the brakelever W is bent laterally, as shown inFig. 3, and carries a ooved .roller- 82 ada ted. to bear against a rake-arm 83' that is c amped as at 84 to the dog-carrier rod 32'. The upper portion of the brake-arm 83- extends for-v wardly orinwardly, as, shown in Fig. 4, and its extreme upper part is cut away as at 85.

The roller 82 rests normally within this out:

away part 85 of the brake-arm 83 and when in such position the friction roller w exerts no braking action upon the frame E of the paper-carnage. As soon, however, as one of the'finger-keys M, M, etc., is depressed to raise the dog-carrier and the dog P, the upward movement of the rod 32 causesthe brake arm 33'to bear upon theroller 82 thereb forcing inward the lower arm of the brake .ever W and swinging u ward its upper arm so that the friction roll w shall bear with more or less force against the under side of the frame E and thus check the too rapid movement of the paper-carriage.- The lost motion between the plate O'and' the dog carrier insures that the brake will be applied before the dog is shifted andbefore the carriage starts on its run. As hasbeen already shown (see Fig. 3), the column-field stops G are disposed upon the sto -bar F with the shortest stops nearest the left-hand end of the paper-carriage. Hence the dog-carrier and the dog P will be liftedto their greatest extent (i. 0., by the key M or M) when the carria e is to have its' shortest free 'run from rig t to left. In this short free run of the apercarriage but a 'slightpressure of the 'ction-roll w is necessary to check the the carriage is to have a longer run from left to right, a more forcible pressure of the-frie tion roll 10 upon the frame E is required, Now by reference to Fig. 4 it will be seen that when the'dog-carrier and the do I are lifted but a short distance, which W11? be the case when thecarria'ge is to have a long free that partof the brake arm 83' immediately below the. cut-away'spae'e 8.5 will bear upon the groovedroller 82 consequently the brake lever W will receive its: greatest shift and the friction roll w will ,bearmost forcibly against the under side ofthe frame E I On the other hand, when; the dog-carrier and the dog P are lifted to their greatest extent, which will be the case when the carriage is to have its shortest free run, the lower partof the brake-arm 83- will bear against the grooved roll 82 and as the inner edge of this lower part of the brake arm 83 inclines rear- -wa-rdly, it is obvious that a less extent of movement will be imparted to the brakelever W and the friction rollw will be caused to bear less forcibly against the under side of the frame E. Preferably, the friction roll 10 Will be of soft rubber or like elastic material capable of being expanded in one direction.

Preferably, the spindle w of the friction roll w, which is adjustably'threaded into the end of the arm WV, carries a dished plate to which is smaller than and bears against the side of the roll w. By adjusting the spindle in axial direction the plate will bear against the central. poftion of the roll so that the latter will be expanded in radial direction to increase its frictional bearing on the bar E.

-From the foregoing description it will be seen that by setting the column-field stops G v at predetermined points along the stop-bar F, the operator, by depressing any one of the finger-keys M, M, etc., can cause the free run of the carriage toward the left, arresting it at the column-field stop corresponding to the finger-keys M, .M, etc., that may be 'depressed. Thus for example, if letters are to "be written upon an ordinary printed lettersheet, the operator will need to insert-the date, the name and address of the party to x whom the letter is to bewritten', etc. ally in about the following form:

r January 15,1902. J. Smith, Esq,

- 15O -Mad1son street,

Illinois. Dear Sir :-Your favor of the 10thinst, duly received, etc.

' Before writing such a letter the operator will set the longest column-field stop G, say at a point on thestop-bar F corresponding to the point designated by the numeral 45 .on the letter-spacescale. and at such point the operator will begin to pfint t lge date, via, January 15, '1902.

The operato will setthe shortestcolumn-field-stop at a point on the stop-bar F corresponding to the point desig nated by the numeral 5.v on the letterspace scale and at such point will begin to 'print the name, vizL, J.

At a point on step bar F corresponding to the oint designated by the numeral 10 on the etter spjace scale, the operator may set the next shortest cdlumn-fieldstop G. and at such point will begin to print the city address,

It will thus ;be seen that the op depressing the finger-keys M, M,

,cause' the-free run of the pa erfi-carriage from' right toward the left, so t at the necessity .20 of advancing the carriage either 1 by the usual manual release 'or by the actuation of stoo of course that the position of. the col umn-field stops G upon the stop-bar F will be i varied corresponding to the character of the i 5 frame Y atthe back of the machine, the bars X being ivoted upon. a transverse rod 12:, as clearly s own in 1 ig. 1,2. The'frame ;Y is connected at its lower end to the base portion of the machine frame and at its upper end is The lower ends of the tabulator bars X. are connected to push rods X thatextend be .neath the base of the machine from back to front and are-held in'the normally retracted 5 position shown in Figs. 1 and 2, b the coilsprings as, these several push rodscaring, at their ends finger-keys X The upper ends a of the tabulator bars Xpass throu h'the upper portion of the frame Y (see *ig.12)'so' o. that when any one of the several finger-keys X is forced inward, theupper end of the'cor; responding bar X will be swung forward into position to engage a rearwas'dly-prfijecting' portion of the denomin'ationalstop these 5 denominational stops H being arranged upon .the stop-bar F in the usual manner at any predetermined points thereon.

that more specifically considered, the stops G and H are column-stops or column-field stops, the former co-o eratmg with the dog P andthe latter with t e stops X,'and that the latter, when more specifical y considered, are denonunational stops, and

' these various stops are thus differently desigchine, but also by mined by thelocation of the stops H1 nated in the claims.

Vlllnle] havedescribed the column stop mechanism and denonnnatmnal-stop mecb:

anism in use in conjunction with one another, 1t will be understood that each mechamsm may be employed w1 thout bringing the other into operation. Thus, for instance,

the column-stop may be used independently of the denominational-stop mechanism where columnar fields alone are to be secured,

and the denominational-sto mechanism may, when desired, be emp oyed' without bringing the column-stop mechanism into operation, so that each mechanism may be operated independently of the other to perform the work for which it is particularly adapted. When 'the column-stop mechanism is employed, a single actuation of a key M,1\I, h etc. is all that is necessary to project the stop P into the path of the proper column-stop G and release the carriage and lock the feedq'ack and projected'stop P in their abnormal ositions; these parts being automatically re eased at the next actuation of'a character key or the space key If, on the other hand, the denominational-stop mechanism is to be employed alone, it is only necessary to actuate push -keys X to arrest the carriage at the proper denominational position within the columnar field deteirn either event no preliminary operation of an auxiliary key is necessary to eliect the proper operation of the tabulating mechanism, whether it be the column-stop mechanism or the denominational-stop mechanism. .It'

should also be noted. that the locking devices for the column stop mechanism are arranged to be released not only by the operation of one of the type bars, orspa'ce bar ofthe mathe operation ofthe denominational stop mechanisml Bythis arrangement, after the column stop m'echan ism isioperated to bring the/carriage to the" desired column field, either the printing "mechanism of the machinenor the denominational sto mechanism may be at once operated and 1n either case noprehn'nnary opera- I tion is necessary to first unlock, the column sto mechanism. i l r t ismanifest that the precise details of construction above set forth may be varied of the invention may be employed Without its adoption asan entirety;
